At first I thought this was the snail I had on my new piece of coral. It came out of the live rock into full view just now. It has two eye stalk type pods up front with what looks like waving hand coral polpys all over it. It is approx. an inch long but can stretch to two inches easily. It moves like a snail with some speed. Here are two different pictures. Sorry they dont capture this thing as well as I hoped.

Note; The intruder is in the middle of both pictures.

My guess would be some type of nudibranch

Mine too. I have been searching for images of these slug type inverts but I haven't found one that look similar. This one can move well and changes colour with it's surroundings. Not drastic changes but goes from beige to light blue in a flash.

Not quite. This one actually really looks like soft coral waving in the water. The eye stalks are not pointy. They look more like the ends of java moss. If this creature didn't move I would swear it was a colony of polyps on the rock.

So the question at hand is, do I remove it (that is if I can find him again),or is it a friendly new addition to the reef?

Think I found my answer. The closest picture I can find is of a,

Tritoniopsis elegans Adult
(Audouin, 1826)

Apparently it's diet consists of soft coral. Explains some things I found tonight. Time to go hunting.

My son found what he thought were some roots growing out of the side of a rock which has my waving hand coral on it. After looking at the "roots" closer I picked up the rock and put it into my specimen container. This is a picture of what came out. I didn't take this pic it's off the net but it looks like the nudi that I sucked off the rock with my baster. The little guy is in a separate container right now. The one I first saw a few nights ago was alot larger then this one so I know there is one more in my tank somewhere. The coral looks 100% better today. The rock still has bare paths on it but the coral is out and waving again.

Thanks Cliff. Have you dealt with these before?

Sorry Strider. The last two tanks I set-up, I recured the rocks in rubbermaid containers to get rid of all the hitch hikers. I have never had to deal with any nudibranches before

Glad to read you haven't been through this Cliff.

I should have quaranteened the coral for more then a day but I thought the source was 100% safe. I spoke with the owner of the store today about what I found in my tank which I'm sure came from the green star I bought off him and he looked over at the display and said, "I was wondering what was happening in there with some of the soft coral."
I finally caught the larger one today so I think I got them all.
Below are pictures of them both in a water bottle which has my tank water in it. They will both be taken to the reef shop tomorrow. Some hobbists actually keep these nudi's and buy coral to feed them.
